Abstract: Preparation of heat-curable, water-dilutable coating compositions based on (A) epoxy resins free from amino groups, (B) an aqueous dispersion or solution of saturated polyester resins or the modification products thereof with oils, (C) organic cross-linking agents and optionally (D) pigments and/or conventional adjuvants, in specific proportions, these components being processed together in one or more stages, while being comminuted from their original particle size, to form a homogeneous coating composition which has a particle size of less than 100 mu m, and the use of the coating compositions thus obtained as coating agents, particularly for coating metal substrates, by the use of current-free methods of application or electrostatic spraying.

Abstract: A water-dilutable binder composition for the preparation of a metallic base paint comprising (A) a water-soluble condensation product derived from (a) a saturated or unsaturated oil-free polyester containing OH-groups having been prepared from at least one polycarboxylic acid and at least one polyhydric alcohol, (b) a polycarboxylic acid mixture containing trimellitic acid, (c) at least one epoxidized oil, and (d) a basic compound; (B) an additive selected from the group consisting of one or more metal powders, one or more metal powders in combination with at least one other pigment, and one or more metal powders in combination with at least one other dyestuff; and (C) at least one water-miscible solvent a process for the preparation of a two-layer metallic paint coating with said composition.
